Webometrics is the quantitative analysis of websites and web-based content. It involves tracking websites, evaluating search engines, and analyzing internal and external links. The field evolved from terms like netometrics, webometry, internetmetrics, and cybermetrics. Webometrics is defined as the study of quantitative aspects of the construction and use of information resources on the web using bibliometric and informetric approaches. The main areas of study are web page content analysis, web link structure analysis, web usage analysis, and web technology analysis. Webometrics is related to other metric sciences like informetrics, bibliometrics, cybermetrics, and scientometrics. Methodologies include selecting a website, using search engines, applying query

 Quantitative Analysis
 Tracking of Website
 Evaluating of Search Engine
 Link Analysis ( Internal and External Link)

4. Evolution of Webometrics
A range of new terms for the emerging research field were rapidly proposed from the
mid-1990s, for example,
 Netometrics (Bossy, 1995);
 Webometry (Abraham, 1996);
 Internetmetrics (Almind & Ingwersen, 1996);
 Webometrics (Almind & Ingwersen, 1997);
 Cybermetrics (Journal started by Isidro Aguillo)
 Webbibliometry (Chakrabarti 2002)

5. Definition of Webometrics
 The study of the quantitative aspects of the construction and
use of information resources, structures and techonologies on
the Web drawing on bibliometric and informetric approaches
is called Webometrics. (by Bjorneborn and ingwersen 2004)
 The study of Web based content With Primarily quantitative
Methods For social science research goals using techniques
that are not specific to one field to study is called
Webometrics. (by Thelwall 2009)

7. Main Areas of Webometric Study
 Web Page content analysis
 Web link structure analysis
 Web usage analysis
 Web technology analysis

8. Relationship between 5 Metric Sciences
 Informetrics : The study of quantitative aspect of information any form
 Bibliometrics : The study of quantitative aspect of production, dissemination and
use of recorded information.
 Cybermetrics : The study of quantitative aspect of internet as a whole.
 Scientometrics : The study of quantitative aspect of science as a discipline or
economic activity.
 Webometrics : The study of quantitative aspect of Web/ Web site.

10. Methodology and Syntax
 Selection of Website.
 Selection of search engines (example AltaVista, Yahoo! , Google, etc.)
 Use of Appropriate query syntax
 Data collection through searching
 Calculation of Web impact Factors
A=Total number of Web pages to a particular site
B=Number of external back links to a given site
C=Number of internal (self) links to a given site
D= Total number of links to a site
WIF_Simple=D/A
WIF_Revised=B/A
WIF_Selflink=C/A

11. Example
 I have search some query using Google search engine.
site:www.jiwaji.edu
Result 11800 pages in jiwaji website
link:www.jiwaji.edu
Result 19 Website to link jiwaji.edu
link:www.jiwaji.edu AND site:www.jiwaji.edu
Result 196 Internal links
Google search engine use on 9-4-2016 timing 5:00 PM
